Revelation 11:1-6

The Two Witnesses 1I was given a reed like a measuring rod and was told, “Go and measure the temple of God and the altar, with its worshipers. 2But exclude the outer court; do not measure it, because it has been given to the Gentiles. They will trample on the holy city for 42 months. 3And I will appoint my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth.” 4They are “the two olive trees” and the two lampstands, and “they stand before the Lord of the earth.” See Zech. 4:3,11,14. 5If anyone tries to harm them, fire comes from their mouths and devours their enemies. This is how anyone who wants to harm them must die.

6They have power to shut up the heavens so that it will not rain during the time they are prophesying; and they have power to turn the waters into blood and to strike the earth with every kind of plague as often as they want.
